HEATING STOVE 0R FURNACE.

SPECIFICATION forming part of Letters Patent No. 367,777, dated August9, 1887.

Application tiled October 29, 1883. Serial No.110,250. ('No model.)

To all whom it may concern:

Beit known that I, EDGAR W. ANTHONY,0f Boston, in the county of Suffolkand State of Massachusetts, a citizen of the United States, haveinvented a certain new and useful Improvement in Heating Stoves orFurnaces, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, forming apart of this specification, in explaining its nature, in which Figurelrepresents my invention as applied to a furnace, and shows inperspectivea portion of thecasing of the stove and a part of theinterior thereof, the section being broken away to expose it. Fig. 2isavertieal section thereof.

Fig. 3 is a view, part in plan and part in section, to illustrate adetail of construct-ion. Fig. 4 shows in vertical section the upperportion of the radiator. Fig. 5 is a section of a plug. Fig. 6 is asection, and Fig. 9 is a plan, of the deflector. Fig. 7 is a section ofthe lower part of the radiator. Fig. 8 is a plan view of the upper part.Fig. 10 is a plan of the lower section of'the radiator.

The invention relates especially to the construction of the radiator,whereby a largera diating-surface is obtained and the heat caused to beuniformly radiated from all sections thereof, and also whereby it may berevolved before it isset, thus providing means for connecting thecombustion-chamber with the smoke-pipe regardless of the position of thefurnace.

It also relates to various details of construction, all of which willhereinafter be more fully specified.

Referring to the drawings, A represents the ash-pit, B the fire-pot, Cthe combustion-chem ber, D the radiator, F the air-heating chamber, andM the outer casing, of the furnace; m,the door to the combustionchamber; m, the ash-pit door; of, the door to the air-heating chamber F.

The radiator D comprises, essentially, three parts: first, the lowersection, (7., second, the upper section, d, and, third, the deflector (1The lower section, d, has the circular flange d surrounding the opening(1*. This flange is adapted to shut into a groove or recess, d cast orotherwise formed in the upper edge of the shell or casting d, formingthe combustionclosed by the plug (1 chamber. From this flange d thesides of the lower section spread outward and upward, but not at thesame inclination, the upper edge of the lower section being curvedinward and outward, as represented in Figs. 3 andlO, so that when thedeflector (Z is in place a series of connected passages, (1 connectingthe combustion-chamber with the chamber within the radiator, are formed.The deflector d is shaped substantially as shown in Figs. 2, 7, and8that is, it is an inverted-cone-shaped plate having a central opening,(1 which is The deflector has a flange, d, which rests upon suitableprojections, d, extending inward from the side of the lower section Iprefer thatthe deflector be shaped substantially as represented in saidFigs. 2, 7, and

S, and when so shaped the passages d in the under section, d, about itare connected with each other-that is, there is a continuous passageabout the radiator, which is enlarged at regular intervals by means ofthe outward turns or curves of the said section. These outward turns orcurves, of course, also increase the heating area of the section.

The deflector is provided with the hole d, in order that soot or dustthat may lodge therein or in the upper portion of the furnace may bedislodged therefrom upon the removal of the plug (i and I prefer not toattach the deflector rigidly by bolting or otherwise to the lowersect-ion, in order that it may be turned or jarred to facilitate suchremoval. The upper section, cl, of the radiator-is shaped tosubstantially the same form as the upper edge of the lower section, andfits into the groove c in the upper edge thereof.

In order that the heat may be caused to be properly deflected by thedeflector-,it is desirable of course that the entrance to the escapeportof the furnace, instead of being located at one side of the radiator-ofthe furnace, as is common, should be arranged centrally over thedeflector, so that the heat may be drawn or ascend from thecombustion-chamber uniformly nponall sides of the deflector, and thiswould. not occur if the entrance to the escapeport were not so placed;and I find that it is more desirable not only to have it centrallylocated in relation to the deflector, as above described, but also tobring it well down from the top of the radiator, in some instancesalmost or quite within the upper edge of the deflector-plate. In thedrawings this opening or escape-port, which is marked E, is shown alittle above the upper edge of the deflectorplate. By this constructionit is obvious that the draft of the furnace will draw the heat or thatthe heat as it ascends will be deflected by the detieetoragainst thewall of the lower section uniformly throughout the extent of thedeflector and in all its passages, and will cause it to strike orimpinge against the side and upper wall of the upper section, fromwhence it wiil take a downward course into the escape-port E. Thisescape-port E, I prefer to have enlarged from its lower edge, e, to thepoint e, where it enters the section, flue, or passage 0 and thissection, flue, or passage may be formed by the flue-plate c", which maybe cast with the upper section of the radiator; or it may be madeseparately therefrom and attached thereto, and it may extendhorizontally therefrom, as represented, and from a somewhat oval shapeassume a cylindrical shape, as represented in Figs. 2 and 4. As manyfurnaces require to be low, this construction will be found to be verydesirable, as it does not increase the height of the furnace and allowsthe connection with the smokepipe to be made at a point below the uppersurface of the casing M; but I do not confine myself to this specificconstruction, because the passage from the escapeport E may extend upthrough the radiator and shell M and then connect with a vertical smokepipe or by means of a suitable elbow with a smoke-pipe having any otherdirection.

By making the flange (1 of the lower section circular I am enabled torevolve the radiator in relation to the shell d, so as to bring thepassage or flue 0* into any desired position in relation to the rest ofthe furnace. Of course, this result would be obtained if the lower andupper sections were circular.

it will be observed that the opening 11 in the deflector-plate can bereached from the opening in? to the combustion -ehamber by means of astick or red, and that the plug can be pushed up and soot easilydislodged from the upper surface of the deflector.

Of course, I can attach the deflector-plate D to either the lower orupper section if I desire, and I may make the deflector of any othersuitable configuration if I wish without departing from some of thefeatures of the invention, although I do not mean by this to beunderstood as not also claiming the deflector and sections in the shapesrepresented.

Of course, thejoints of the furnace between the two parts of" thedeflector and the lower section of the deflector d, are packed in theusual manner after the radiator has been located to bring the flue a"into proper position.

Having thus fully described my invention, I claim and desire to secureby Letters Patent of the United States- In a heating stove or furnace,the combination of the section (1 of the radiator, the plate 0, formedintegral therewith and shaped to provide the-horizontal central opening,E, and the lateral passage 0' from said central opening to the exteriorof the stove or furnace, the section (Z of the radiator, having flutedsides, as described, and the circular flange dffland. thedeflector-plate (1", arranged within and supported by the section (I ofthe radiator, as and for the purposes described.
